Silt Curtains UK have installed several moonpools in the UK, also Columbia, and Lithuania. Aquatic Engineering designed and fabricated this bespoke 94m long by 8.4m deep ballasted moonpool to completely enclose the purpose-built L&W pontoon. Thus, contamination was prevented from leaching into the River Fowey during the dredging operation. The curtain, weighing more than 1.5 tonne was installed by a team of 15 men including 4 divers largely in one day, despite the tide variations which hampered the process somewhat.

The Marina site falls within the Fal-Helford area, a SSSI, however the site formerly occupied the Empire and Kings wharves and had not been dredged since 1938 almost 10,000m3 of highly contaminated material containing heavy metals toxins such as TBT – which experts claim is the most toxic substance ever deliberately introduced into the marine environment – needed to be removed from site… The moonpool was the obvious and successful solution.

Moonpools are site and system specific and require considerable engineering time input to be workable and effective.
